How do i charge my makita lithium battery with a hyper tough charger?Someone stole my makita 18v lithium battery charger. I really need my drill at the moment.

Yes, because the voltage and amperage input to the charger is constant, so the board management dumps excess charge once the battery is fully charged. The battery cools, but the charger warms up. Mine does the same. It is a 15 minute charger, so the current is high.

Battery is shot. Replacements are $75 - $100. If its new you have a 1 yr warranty.

I do not about a Makita, but my experience with other brands is when that happens, it means the battery is no good and needs replacing.

This isn't true because I have a second charger and it works fine

If the charge count on the batteries is under 300, Makita will replace them. Makita has a known defect in this battery that causes the battery to shut down before it is dead. So as of now they are exchanging ones with low use.

If they are truly defective and makita won't replace, you have to open them, find the dead cell or blown fuse, and replace. Search youtube makita battery for a video on repairing this battery. But once the red and green lights on the charger flash, the the battery can't be charged on a Makita charger -- it's been locked. So use a third party charger.

Sorry Mate your battery is dead...
The makita lithium batterys dont like getting worked hard quickly.
There is a chip in them that recognice each battery to each specific charger. Try another charger. This has not worked for me. Try anyway

the lithium batteries are not like nicad you can cahrge them whenever you want and will not get a memory. Just put them on the charger and when the ready light is on they are done.

looks to me like a defective batterie

of course
